I control my (soon to be built) observatory with a single windows laptop. The 1600 is not installed yet but when it is will I be able to use PemPro on both the mounts from the single computer? The 1600 came with a full version of Pempro version 2.x. Can this version be updated to version 3 for free? I do realize AP configured PemPro before shipping the 1600, I just want to understand my situation.
